Application filed February 5, l890 Serial No. 339,307. (No model.)

To @ZZ whom, t may concern: low of the rolling of the rollers 13 and the Be it known that I, ERNEST 'WILLIAM axle 2l within the said bore 3. COOKE, a citizen of the United States, resid- On the end of the journal-box at one end I ing in Chicago, county of Cook, and State of fit a cap or cover 5. This said cap is drilled 5 Illinois, have invented a new and useful Imat convenient points and provided with a 55 provement in Journal-Boxes, of which the screw-thread, which is made to accommodate following is a specification. the take-u p screws 7. These take-up screws My invention relates to journalboxcs in 7 have on their points a pit for holding the which a shaft is held between a series of rollball 9. These take-up screws 7 are held in 1o ers, the said rollers being supported by a seposition by the lock-nuts S. The cap 5 is 6o ries of rings secured together by rods, and bolted to the body 1 by the bolts 6. The which said rings revolve about the shaft, the outer end of the cap 5 is bolted by the bolts lateral motion of the said rings being taken 1G to the cover or plate 15, which cover 15 up by balls held in pits of set'screws, said has a hole in the center threaded to provide t 5 screws being secured by: a nut.

Vithin the said cap ries of balls. The one ball is held against 5 is a cylindrical bore, and on the inner face 2o the series of balls by a plate, spring, and setof the plate 15 is a cylindrical pit of equal 7o screw, which is fastened to the outer cap of diameter with the bore of the cap 5. the box.

The ring 10 is united with one of each end of the journahbox I provide applisimilar construction at the other endof the 95 ances for bolting on caps 5 and 25. lVithin box 1. These said rings 10 are united to each the journalbox at each end Idrill out chamother by the rods 1l, which run horizontally, ber el larger than the bore of the center of and the rods 14C are pinned tothe rings by the j ournal-box. The bore in the body of the the radial pins 11. 5o jcurnahbox is of a size just sufficient to al- At a convenient point in the outer surface roo of each of the rings 10, I make an annular groove, against which said groove the balls 9 revolve, they being held in the pit at the end of the take-up screws 7.

At'convenient points in the rings 10, I insert a series of pins 12, which serve as the pivots about which roll the rollers 13. The pins 12 are held firmlyin place by the radial pins 1l.

At the outer end of the box 1 I place a cir cular cap or stufiing-box 25, which incloses the shaft 24; and is secured to the box 1 by the bolts 6. At convenient points the cap 25 is drilled with holes and threaded for the reception of the take-up screws 7, which carry the balls 9. rllhe said take-up screws 7 are secured in place by the lock-nuts 8. I bore out the center of the cap 25, and into it I fit a gland 27, which is made to lit the shaft 24 closely and the whole of the cap 25. In the end of the gland 27 I place a packing 2S, which is held tight around the shaft by the gland 27 and compressed so as to keep any lubricant I may place in the boX from escaping. The gland 27 is secured to the cap or stuffing-box 25 by bolts 26.

At each end of the box 1 I enlarge the diameter of the bore for the purpose of giving clearance between the'outside diameter of the rings and the inside diameter of the box.

Having now described the parts of my invention, I proceed to explain the method of using the same. I put the parts together so that theshaft 24; shall revolve within the rings 10, rods 14:, and rollers 13, the ends of the rollers 13 being held by the pivot-pins 12. The said rings 1() roll against the metallic balls 9, which balls 9 are held by the take-up screws 7. all the slack between the rings 10 and the take-up screws 7 is taken up, whereupon the lock-nuts 8 are secured, so as to prevent the take-up screws 7becoming loose. The end of the shaft carries the three balls 22 in the pit 23, and a fourth ball 2l is held against the three balls 22 by the bearingplate 20, which is held up against the ball 21 by the spring 19, which is rendered more or less tight by means of a take-up screw 17 acting on the plate 1S. The take-up screwl is secured by the lock-nut 17. The space within the box l is filled with a fluid lubricant after the caps 5 and 25 have been bolted to the said box 1 by the bolts (5. The gland 27 is then adjusted by the bolts 2G, so that the packing 2S is compressed and prevents the lubricant from escaping.

I am aware that journal-boxes have been The screws 7 are adjusted so that' used prior to my'invention, and I do not therefore lay cla-im in a broad sense of journalbox; but

That I do claim, and desire to secure by Letters Patent, is-

1. In combination with a shaft having a pit in the end thereof, a roller-bearing surrounding said shaft, a series of balls placed in the recess in the end of the shaft, a single ball adapted to roll against the series of balls, and a bearing-plate having a pit to retain said single ball in position, all substantially as and for the purpose set forth and described.

2. In a roller-bearing, a casin g, collars therein provided with pins entering recesses in the ends of the rollers and supporting the latter, and means passing through the ends of the casing for independently adjusting said collars, all substantially as and for the purpose set forth and described.

3. In a roller-bearin g, a Casin g, collars therein provided with means for supporting the rollers and having pits in their ends opposite the rollers, balls seated in said pits, and means for holding said balls in their pits, all substantially as and for the purpose set forth and described.

4. In a roller-beari n g, a Casin g, collars therein provided with means at one end for supporting' the rollers and with pits on their opposite ends, screws passing through the casing and provided with pits in their ends, and balls seated between said collars and screw ends in the pit-s thereof, all substantially .as and for the purpose set forth and described.

5. In combination with a shaft having a pit in the bend thereof, a roller-bearing surrounding said shaft, a series of balls placed in the recess in the end of the shaft, a single ball adapted to roll against the series of balls, a bearing-plate having a pit to .retain said single ball in position, and means back ofv said bearing-plate for yieldingly retaining and adjusting it, all substantially as and for the purpose set forth and described.

6. In combination with a roller-bearing having collars provided with pins for supporting the rollers and allowing them to revolve thereupon, and balls bearing against the end of the shaft, a lubricant-tight casing provided with means in its ends for adj usting the collars and rollers, all substantially as and for the purpose set forth and described.
